摘要 文本分类技术是知识管理系统实现知识有效组织、存储和检索的重要手段,而基于词向量空间模型的文本分类没有考虑知识管理系统的特点,从而也不能满足知识管理系统中多分类的需要。论文提出了一种新的基于知识本体的文本分类算法,该方法利用知识管理系统中的本体集,实现了多概念粒度分类,实验表明该方法具备良好的分类性能。 In the knowledge management system, text classification technology is an important means of organizing, storage, and retrieval for the knowledge. The traditional text classiication technology is difficult to meet the needs of the knowledge managemetn system. In this paper, a new ontology-based text classification algorithm is presented, which takes full advantage of the knowledge management system featrues and implements the multi-granularity classification for the concepts. The experiments show that the method has a good classification performance.
